Multipurpose Gasket for a Rigid Coil in a Switched Reluctance Motor

A system for assembling a coil on a pole of a stator, the system comprising:

• a coil guide configured to be disposed over an inner surface of a pole, the coil guide including a rectangular cross section in a plane orthogonal to a radial line passing through a midpoint of the pole and a U-shaped cross section in a plane parallel to an end plane of the stator, an open end of the U-shape facing the pole, the coil guide further including a plurality of notches, each notch configured to receive a corresponding coil spacer and opening away from the pole;
• a plurality of corresponding coil spacers, each coil spacer configured to be snugly and removably disposed in one of the plurality of notches;
• and
• a gasket tool configured to receive a gasket, to place the gasket over a coil and, with the gasket disposed between the coil and the gasket tool, to fit the coil, the gasket, and the gasket tool over the pole, the coil guide, and the plurality of coil spacers, and to correctly dispose the gasket and the coil over the pole.

A method of assembling a stator, the method comprising:

• placing a coil guide onto a radially inner portion of a pole of the stator;
• inserting each coil spacer of a plurality of coil spacers into a corresponding notch of a plurality notches in the coil guide;
• placing a gasket onto a gasket tool;
• placing the gasket and the gasket tool onto a coil with the gasket disposed between the coil and the gasket tool;
• placing the coil, the gasket, and the gasket tool over the pole;
• removing the coil guide, the plurality of coil spacers, and the gasket tool from the pole;
• repeating steps recited above for at least one adjacent pole;
• inserting, from a detachable tab end of each gasket, a wedge into a wedge groove between each pair of adjacent coils, poles, and corresponding gaskets, fitting each wedge securely between each pair of adjacent poles;
• and
• removing the detachable tab from each gasket.
